Via above explanation as can be known, known vehicle Shock absorber mainly is to utilize to adjust the mode that the high and low position of nut 102 is adjusted at elastic element 30 tops, reaches the shock-absorbing intensity of adjusting elastic element 30 tension force; But, adjustment nut 102 backs through this novel creator's practical operation, the known vehicle Shock absorber of rotation are found, the adjustment nut 102 of known vehicle Shock absorber is when operation, often have and adjust the phenomenon appearance that nut 102 can't rotate, and this kind adjusted the phenomenon that nut 102 can't rotate, can be obvious more when adjusting nut 102 more near positioning seat 201 (being that elastic element 30 oppressed outside tension force are big more), perplex greatly when causing operation.Referring to Fig. 3,4, study known vehicle Shock absorber and why can produce the phenomenon that adjustment nut 102 can't rotate, the creator finds that its major cause is, because elastic element 30 will be born vehicle and rider's weight, so need structural strength and crushing resistance utmost point powerhouse to be competent at, thereby, when adjustment nut 102 is got over pressuring elastic element 30, the tension force that elastic element 30 desires are recovered the extratensive type attitude is strong more, so elastic element 30 will produce one extremely strong F of thrust vertically upward
A, its end face all the more is tight against is naturally adjusting nut 102 bottom surfaces, rotates the external force of adjusting nut 102 and then forms one horizontal cross torsion F
B, add the bottom surface of adjustment nut 102 and the end face of elastic element 30 and (promptly adjust nut 102 and elastic element 30 mutual binding faces of fitting, as shown in Figure 4) be smooth side, so the friction force of the two is almost nil; Thus, will produce because adjust the vertically upward tension force of the horizontal cross torsion of nut 102 much smaller than elastic element 30, i.e. FA＞FB, and then the situation that causes the operator at all can't rotate adjustment nut 102 occurs, and it is inconvenient greatly to cause operation to go up.
Summary of the invention
In view of this, creator of the present utility model satisfies design and researches and develops at known vehicle shock absorber structure, and the phase is at one's best its structure, and through studying design and modification back for a long period of time appearance of the present utility model is being arranged.
The purpose of this utility model is for a kind of vehicle Shock absorber is provided, and it can rotate smoothly adjusts nut to adjust the shockproof effect of Shock absorber.
Show purpose for reaching, a kind of vehicle Shock absorber of the special design of creator of the present utility model has the axostylus axostyle and that a liquid gas pressure cylinder, is located in the liquid gas pressure cylinder and is set in liquid gas pressure cylinder and the exterior elastic element of axostylus axostyle; Wherein, liquid gas pressure cylinder outer shroud wall forms thread segment and establishes for adjusting the nut spiral shell; And the axostylus axostyle bottom is provided with a positioning seat, and the top of elastic element and bottom are replaced respectively and adjusted nut and positioning seat; It is characterized in that: adjust nut handling through surface coarsening, form coarse face of joint towards the end face of elastic element.
Adjusting nut because of the utility model is handling through surface coarsening earlier towards the end face of elastic element, form coarse face of joint, thereby improved the friction force of adjusting between nut and elastic element face of joint, the horizontal cross torsion of adjusting nut is increased greatly, adjust the nut displacement to adjust the shockproof effect of Shock absorber thereby can rotate smoothly.
